The first end-credit scene

We're back at the X-Men mansion with Negasonic Teenage Warhead (Brianna Hildebrand) and her girlfriend Surge (Shioli Kutsuna). They're trying to fix Cable's device which allows him to travel through time.

He tells Deadpool earlier in the film he conveniently only has enough power to use the device twice — once to travel to the past and once more to return home. However, once he uses it at the film's end to save Deadpool, he's stuck at that point in time.

He doesn't seem too worried about sticking around for a while longer.

Deadpool walks in on Negasonic Teenage Warhead and Surge just as they put the finishing touches on the device. Deadpool, ever the pal, asks to take the fixed device to Cable. The two oblige before realizing they probably made a mistake.

"What have we done?" asks Warhead before the scene ends.

What it means

Could we see Cable time traveling again? Marvel/Fox

We'll get to the second end-credits scene in a moment, which shows the immediate effect of Deadpool taking the time-traveling device. But the introduction of Cable's tech invites a lot of exciting opportunities for future movies and storylines.

For one thing, Cable could head back to the future at some point to be back with his family. But like he said, he's in no rush to head home. (Sorry Cable's wife and kid. He seems to like Deadpool a lot.)

In the meantime, if the device is to get used, we could see Cable travel through time with Deadpool and the other members of the X-Force, especially if they're needed to help save the world — or the main "X-Men" cast from trouble. Or we could just see them traveling through time in their own self-contained stories. That idea is similar to what DC's "Legends of Tomorrow" currently does on the CW. The show features a ragtag group of heroes and past villains from other shows traveling through time to save the world. Twentieth Century Fox may want to go for something more original.

If Hugh Jackman was game, the group could even travel back in time and stop Wolverine from dying. Since Deadpool seems to be a massive fan of the character, it doesn't seem like the most absurd idea, even if he was resurrected just for one movie. (But that's just a lot of us hoping to see Ryan Reynolds and Hugh Jackman together for more than a "Deadpool" movie promo.)

Either way, the possibilities seem endless with the introduction of a time travel.

The second end-credits scene

What happens

Deadpool goes on a time travel spree! 20th Century Fox

This is where things get fun. Instead of wondering, we get to see Deadpool use the time travel device in four different sequences. Each one is better than the last.

The first scene shows Wade Wilson go back in time to the start of "Deadpool 2" where he saves his girlfriend Vanessa (Morena Baccarin). He tells her that they're definitely naming their child Cher.

He then returns to the scene where his newly-assembled X-Force team gets axed. Instead of saving every character who died earlier in the film, including Brad Pitt's blink-and-you'll-miss-it cameo, he saves Rob Delaney's powerless character Peter. (Deadpool really has a soft spot for him.)

Things then get ludicrous.

The film flashes back to 2009's "X-Men Origins: Wolverine" movie. We see a scene play out that was in the original film. Jackman asks Wade if that's him and notes that Stryker — the man who turned them both into mutants — finally found a way to shut him up. We then see Reynolds as the version of Wade Wilson that appeared in the film. His mouth is sewn shut and there are weird marks all over his body. He's not wearing the Deadpool suit. It's a far cry from the Wade we know on screen today.

Deadpool has seen better days. 20th Century Fox

Before he can respond, Deadpool pops up and kills the character before anything is able to happen. Deadpool says he's just "cleaning up the timelines." He does so to Cher's "If I Could Turn Back Time."

We then see actor Ryan Reynolds excitedly looking over a script he just received. The camera pans to show he's looking at a script for Warner Bros.' 2011 "Green Lantern" movie. Before anything else can happen, Deadpool steps in and shoots Reynolds dead.

What it means:

Deadpool is just fixing some things he doesn't think should have occurred in history. Marvel/20th Century Fox

Most of these are just funny gags with Reynolds finally getting to lay to rest any issues he may have been holding onto about previous roles.

Reynolds originally played a very different version of Deadpool's Wade Wilson in the critically-maligned "Wolverine" movie. The character, who is usually rather chatty, was shown with a sewn up mouth to prevent him from talking, and a skinned head. His swords were fused into his hands to look like two giant claws. Fans were very vocal about how the movie studio butchered the beloved character.

It's not all terrible. The role did allow him to meet his current wife Blake Lively on set. Reynolds has said she's his best friend and helps keep him "sane" when dealing with anxiety.

The first two scenes with Peter and Vanessa are interesting, though.

It's not clear whether or not the scenes will have any lasting impact on the future of the franchise. Is Vanessa alive again and could she possibly appear in future movies? What about Peter, who admittedly has zero superpowers, but was a member of Deadpool's original X-Force team? They're probably staying dead, but it would be a good excuse for either to show up again down the line.
